DTC P16E7: General Description
The local interconnect network (LIN) line connects the 12 volt battery fan motor and the powertrain control module (PCM). The LIN uses a master/slave protocol to send and receive data to the different components on the line.The PCM is the master unit, which controls the engine electrical system. The 12 volt battery fan motor is the slave. The 12 volt battery fan motor receives data from the PCM and provides feedback to the PCM, which allows the PCM to operate the engine electrical system efficiently. When the PCM does not receive signals from the 12 volt battery fan motor within its specified amount of time, the PCM detects a malfunction and stores a DTC.
